Emerson has announced the release of its new Fisher FIELDVUE DPC2K digital process controller (DPC2K).

According to the company, the DPC2K can be retrofitted to Fisher Wizard pneumatic controllers, and to pneumatic controllers from other manufacturers.

The DPC2K also reportedly provides numerous connectivity options, enabling remote setpoints, remote access for configuration, monitoring and other features.

The DPC2K can be retrofitted as a direct replacement for the pneumatic controllers installed on most valves, regardless of manufacturer. Closed loop control is improved with configurable loop types, over 150 units of supported measure, 20 times per second (50 milliseconds) scan and update rates, configurable dead band, anti-reset windup, dynamic reset limiting and other features. These features keep the process variable — typically pressure, flow, level or temperature — close to setpoint, along with greatly improved recovery from saturated conditions.

The DPC2K is designed to maintain its high level of performance for years with no required maintenance, and when maintenance is required, it is easily performed using modular replacement components. Another important advantage from this upgrade is the ability to easily interact with the DPC2K locally or remotely. Local interactions are performed via its menu-driven LCD and six-button user interface, with four buttons used for navigation and two for operator input.

The DPC2K has inputs, outputs and intelligence to perform local closed-loop digital control using the proportional-integral-derivative (PID) controller. It can accept a 4-20mA input from a two-wire or four-wire instrument, typically the process variable (PV). For pressure control applications, an optional pressure sensor can be used to provide the PV.

Fisher LoopConnect software provides comprehensive remote access, including configuration and monitoring, networked or direct Ethernet connection, and alerts for troubleshooting. Options include integral, sealed gauge pressure sensor with 0 to 30, 0 to 100, 0 to 300, 0 to 600 or 0 to 1,500 psig range; and pneumatic output with low bleed of less than 3.0 standard ft³/h.

Because the DPC2K is configurable, the same base model can be used in a variety of applications, including pressure, flow, level, temperature, percentage, volume and rate control. The DPC2K is rated for use in Class 1 Division 1 or Zone 1 hazardous areas, and it has an operating temperature range of -40° C to 80° C inputs of 9 to 28 volts direct current are accommodated, with a typical power draw of only 1 W.
